Comparison of Lateral Pile Behavior under Static and Dynamic Loading by Centrifuge Tests
The p-y curve method considering non-linear soil-structure-interaction is most frequently used when the pile foundations are designed for lateral loading conditions. In this study, a series of centrifuge tests was carried out on a pile foundation in dry sand to analyze the lateral pile behavior for static loading and dynamic loading conditions. From the result of the comparison of experimental p-y curve with API p-y curve, it was confirmed that the static API p-y curve underestimated the displacement of the pile, where the ultimate subgrade resistance ( Pu ) occurred, by approximately 80%. In addition, the static API p-y curve underestimated the ultimate subgrade resistance ( Pu ) compared to the experimental static p-y curve by up to 20%. In the case of the dynamic loading condition, the cyclic API p-y curve significantly underestimated the subgrade reaction by up to 80%. Therefore, pseudo-static analysis with the cyclic API p-y curve for seismic design would cause overly conservative design.
